GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 452,256, dated May 12, 1891.

Application filed February 26, 1889. Serial No. 301,271-

To all whom it may concern:

Be it known that I, EDWARD BROOK, a subject of the Queen of Great Britain and Ireland, residing; at Rashcliffe, Huddersfield, in the county of York, England, have invented certain new'and useful Improvements in Gas- Producers, (for which I have obtained a patent in Great Britain, No. (3,454, dated May 1, 1888,) of which the following is a specification.

According to this invention a gas-producer of the kind in which a water channel or jacket is included in the wall has one or more tuyeres arranged to project from the said water-jacket into the fuel or fire. Across the base, which may contain water, I place a cross-bar for the purpose of occasionally supporting temporary bars. To facilitate thelighting of the fire or the complete removal of clinker and ashes from the ash-pit, I arrange an opening or a series of openings on two opposite sides of the producer at or a little above the level of the cross-bar, which openings are kept closed when temporary bars are not inserted. To facilitate their closing it is convenient to make them in the form of boxes with flapdoors. Through these openings I pass temporary bars of iron, whose inner ends rest upon the cross-bar, and I am thus enabled to light the fire on a temporary grate and withdraw the same at pleasure; also, when the producer is at work the bars will support the fire while the clinker and ashes are thoroughly cleaned out. I prefer the cross-bar to a solid wall or support, although I sometimes make use of the latter, as I am enabled to push the poker, rake, or shovel underneath and through to the other side, which a solid support would prevent.

In place of admitting the air to the center of the fuel through a tuyere, it may be delivered from a hollow bar, bridge, or channel passing across the lower part of the producer at about the Water-level. This bar, bridge, or channel, besides serving as an air-inlet, fulfills the function of the cross-bar mentioned above. It is open at the bottom,'which dips into water, while at the sides it has perforations or outlets for the emission of air, which is forced into it byasteam-jet or other blower. The iron channel being open at the bottom,

and only being partially immersed in water, allows any clinker or other solid matter that may fall or run into the perforations to drop through onto the floor instead of choking up the passage. It also permits of the poker, rake, or shovel being passed underneath it, thus providing access to all parts of the hearth, as well as giving more space for the accumulation of ashes. The fact that the channel is partly immersed in water preserves it from being injured by the heat of the fuel and prevents clinker sticking to it. When the tuyeres are-not employed, the water channel or jacket in the wall may be dispensed with, the lower part of the producer being parallel or tapered inward.

The accompanying drawings show gas-prod ucers according to my invention.

Figures 1 and 2 on Sheet 1 are respectively an elevation, partly in section, and a sectional plan of one arrangement. Figs. 3 and 4 on Sheet 2 are similar views of a modification of the apparatus, and Figs. 5 and 6 on Sheet 3 both represent in sectional elevation further modifications thereof.

Referring to Figs. 1 and 2, IV is the water jacket or channel provided with the tuyere T, which projects into the fire and admits air thereto by the internal pipe extending through the water-jacket to the outer air, where it may be connected to the annular blast-chamber B under the water-jacket or be provided with'its own steam-blower.

B is the annular blast-chamber, having air supplied to it by the steam-blower S, and from which chamber the air passesinto the fire, urging combustion in the outer portion of the same.

0 is the central cross-bar or air-channel extending from side to side across the center of the producer, and upon which the points of the temporary bars (shown in dotted lines) rest when inserted for the purpose of holding up the fire. This cross-bar or channel is partly immersed in the water at the bottom, and is thus kept cool, while clinker is prevented from sticking to it.

0 O are the openings or slots for the passage of the temporary bars, and are closed by the swing flaps or doors D, which also close the openings for removal of ashes and clinker.

The doors D are swung or hinged at the top, and their lower edges dip into and are luted by the water at the bottom.

\Vhen desired, the tuyere T may be dispensed with, the air being then admitted to the center of the fire through the crossbar U, which is perforated near the center, so as to insure the air being passed into the fire at that point, as shown in Figs. 8 and ion Sheet 2, where it will be noticed the annular waterjacket \V and the tuyere T are absent, the whole of the air for combustion being passed into the fire through the central cross-bar or air-channel C by means of the side openings E at the center, as indicated by the small arrows. These openings E are purposely placed near the center, so as to keep the air away from the side walls and to cause it to pass through the body of the fire. The water on the floor seals the bottom of the cross-bar or air-chann el O, and thus prevents the air from escaping into the fire at any point, excepting through the openings E. One end of the cross-bar or channel 0 is connected through the side of the pooducer with an ordinary steam-jet blower S.

The ashes and clinker collect in the water upon the floor of the producer and are removed from time to time through the doorways D D, the temporary bars being inserted meanwhile through the slots or openings 0 0 whenever requisite.

Figs. 5 and G on Sheet 3 are two further modifications, both having the central crossbar or air-channel C cooled by water, as previously described; but the floor of the producer is not covered with water, the fire resting directly upon the brick base. In Fig. 5 a small channel A is formed in the base, so as to connect the water-troughs M M at the outside with the water-trough under the airchannel 0. The lower edges of the doors D D dip,as before described,int-o and are luted by the water, whereas in Fig. 6 these doors are entirely out of water.

Having described the nature of my said invention and in what manner the same is to be performed, I hereby declare that what I consider to be novel and original, and therefore claim, in a gas-producer is 1. In a gas'producer, the combination of the producing-chambcr having the solid or stationary floor,thc hollow cross-bar (i, horizontally arranged on said floor, a water space or channel, said cross-bar being located in the water-channel and so arranged and constructed that the water extends up into said bar 0, preventing said. bar burning and clinker adhering thereto, and means, substantially as described, for supplying air or steam into said producing-chamber, substantially as described.

2. In a gas-producer, the combination of the chamber having a normally-closed bottom, temporary grate-bars, the hollow metal crossbar extending centrally and horizontally across said bottom, having perforations in its upper portions arranged to deliver air or steam beneath the temporary grate-bars, means, substantially as described, for maintaining water within said hollow cross-bar, means, substantially as described, for supplying air or steam to said cross-bar, the openings opposite said cross-bar forthe insertion and withdrawal of the temporary grate-bars, and flap-doors D, normally closing said openings, as set forth.

3. The combination, in a gas-producer, of the chamber h, the water bottom thereof, the hollow metal cross-bar C, open below and extending horizontally and centrally across the bottom of said chamber, with its lower side extending into said water bottom, means for supplying air or steam to said bar C, temporary grate-bars, openings in said bar to deliver air or steam beneath the temporary gratebars, side openings 0 O opposite said crossbar to admit-insertion and withdrawal of the temporary grate-bars, and exterior flap-doors D D, normally closing said openings and at their lower ends dipping into said water bottom, as set forth.

In testimonywhereofl have signed my name to this specification in the presence of two subscribing witnesses.
